The AeroVee features dual ignition, using two spark plugs per cylinder and including four independent, solid-state ignition modules, all driven directly off the crankshaft/flywheel assembly. The AeroConversions secondary electronic ignition provides extremely reliable starting under the toughest conditions, while adding "dual-plus" ignition reliability by completing the AeroVee's quadruple-redundent ignition system.

The AeroVee 2.1 represents thousands of hours in engineering, machining and testing and the AeroConversions design team has over 35 years of experience in pioneering and innovating VW engine conversions. The modern AeroVee engine design has thousands of customer-flown fleet hours to its credit, with installations in a wide range of airframes.

2002: AeroConversions re-introduced the AeroVee brand to the marketplace with unveiling of the AeroVee 2002, a truly modern VW aircraft conversion utilizing simple and elegant design, high-quality VW core parts, the most robust prop hub assembly installation in the VW conversion marketplace, the latest CNC machining technology and applying a broad history of VW engine conversion design and testing experience.

December, 2003: AeroConversions introduced the AeroVee secondary electronic ignition, giving the AeroVee dual ignition, improving power and starting, and increasing the total number of independent ignition modules on the AeroVee Engine from 2 to 4, making the "dual-plus" ignition system used today. Dual Ignition Upgrade: Most older, single-ignition AeroVee engines (those produced after 2002) may be upgraded to dual ignition.

The new Machined Oil Breather Plate offers higher breather volume and better durability over the previous PVC breather elbow. Existing AeroVee customers may purchase this part as an upgrade.

March, 2008: Introduction of AeroVee 2.1. Due to the increasing volume of AeroVee engine sales, we have been able to incorporate new features that enhance the already robust AeroVee design. The new AeroVee 2.1 features a purpose-built custom crankshaft that has a larger diameter and longer prop hub interface. This new design also eliminates the distributor drive gear and the racer spacer, making for an easier assembly. AeroVee 2.1 continues to use standard bearings, eliminating the need for custom bearings and allowing for easy replacement at overhaul time. All external steel conversion components are also now zinc plated for improved aesthetics and additional corrosion resistance.
